How do I start investing with very little money?

Start with a micro-investing app like Acorns, Stash, or Robinhood, which let you invest with as little as $1. These platforms allow fractional shares, meaning you can buy a piece of expensive stocks like Apple or Amazon without needing hundreds of dollars. Set up automatic small contributions, even $5 or $10 a week, and it adds up over time through compound growth. Focus on low-cost index funds or ETFs rather than picking individual stocks, since they spread risk across many companies. If your employer offers a 401k with matching contributions, prioritize that first since it's essentially free money. The most important thing is simply starting early, even with tiny amounts, rather than waiting until you have more.
